rake db:create doesn't create the database

[mariuz]

I had to create it manually

rake db:create
/var/lib/firebird/2.5/data/demo_app.fdb already exists
rm /var/lib/firebird/2.5/data/demo_app.fdb
rake db:create
rake db:migrate
rake aborted!
Error opening database connection.
I/O error during "open" operation for file "/var/lib/firebird/2.5/data/demo_app.fdb"
